Ace: Okay. And even though me and my friends want to deliver this book to you.

Kululu: Oh. That book. So Giroro, want you to bring this. Thank you. You wish to know about what kind of book this is? I don't even know, myself. In fact, it's not mine. Somehow it found its way Into my bag one day. It was such a curious book, I asked for to repair it for me. Well, I guess I'll put it here somewhere, for now. This Book holds a great secret. The missing pages will unlock it. I'll leave the book over there. Do look at it whenever you like. My best regards to Giroro for repairing it for me. Oh, and about that stone of yours... You should ask Keroro about that.

Ace: Do you have any idea what this is?

Keroro: Oh no, he trapped in here. He has turned into a summon gem.

Ace: What's a Summon gem?
